Whether you're hitting the open road for extended adventures or upgrading your RV lifestyle to a new level of elegance, the 45D delivers an unmatched blend of power, technology, and comfort.

Why the 2026 Entegra Coach Cornerstone 45D Stands Out
1. Elite Power and Performance
Built on the proven Spartan K3 chassis and powered by a robust 605HP Cummins X15 diesel engine, the Cornerstone 45D offers superior torque, control, and ride stability. With tag axle support, independent front suspension, and VIP Smart Wheel steering, this coach delivers a smooth, confident driving experience—even at full capacity.
2. A Residential Experience On the Move
The 45D's floorplan is brilliantly designed for those who love both luxury and functionality. It features dual opposing living room slides, a bath-and-a-half layout, a king-size rear bedroom suite, and expansive wardrobe space. The living area offers power theater seating, a fireplace, and integrated entertainment center for total relaxation, while the kitchen shines with solid-surface countertops, a residential refrigerator, dishwasher, and induction cooktop—ready for your gourmet creations.
3. Tech-Savvy and Smart Living
Take control of your entire coach with the VegaTouch Mira system, allowing you to manage lighting, HVAC, shades, and more right from your smartphone or tablet. Integrated mobile Wi-Fi, premium audio systems, and multiple smart TVs make it easy to stay connected and entertained, wherever the road leads.
4. All-Season Ready, All-Comfort Included
Equipped with triple 15,000 BTU A/Cs, Aqua-Hot 600D hydronic heating, and double insulation, the Cornerstone is ready for all climates—whether you're chasing the sun or snow. Enjoy year-round travel without sacrificing comfort or control.
5. Exceptional Craftsmanship Everywhere You Look
From hand-laid porcelain tile floors to high-gloss hardwood cabinetry and premium Villa furniture, every inch of this coach is crafted with precision. LED accent lighting, soft-close drawers, and upscale finishes create a luxurious, high-end feel that redefines what RV travel can be.
